Connector device for substrate

The purpose of the present invention is to improve workability when separating a substrate. A substrate connector device is provided with: a main substrate (10); a main connector (16) mounted on the mounting surface (11) of the main substrate (10); a sub-connector (30) having a second sub-substrate (35), the second sub-substrate (35) being attached to the main substrate (10) in a state of being connected to the main connector (16); and a holder (50) provided to the sub-connector (30), the holder (50) holding the sub-connector (30) in a state in which the sub-connector (30) is attached to the main substrate (10) by being engaged with the main substrate (10), and the holder (50) being capable of separating the sub-connector (30) from the main substrate (10) by being separated from the main substrate (10). 实现基板脱离时的作业性的提高。基板用连接器装置具备：主基板（10）；主连接器（16），安装于主基板（10）的安装面（11）；副连接器（30），具有第二副基板（35），将第二副基板（35）以与主连接器（16）连接的状态安装于主基板（10）；以及保持器（50），设置于副连接器（30），通过卡止于主基板（10）而将副连接器（30）保持为安装于主基板（10）的状态，通过与主基板（10）分离而使副连接器（30）能够脱离主基板
